Cometic
multi-layer steel (MLS) head gaskets are comprised of three layers of stainless steel. Cometic uses
stainless steel for increased strength, it's ability to rebound, and
improved corrosion resistance. The outer layers of the gasket are
embossed and coated on both sides with Viton rubber to meet the demands
of a variety of harsh sealing environments, load conditions and surface
finishes.
Cometic's
Viton coating is heat resistant to 250°C or 482°F. By design the MLS
gasket promotes an even torque across the sealing surface allowing for
measurable reduced bore distortion.
